Approval doesn't mean achievable.
At this point, 160 Starship launches in 2026 would be close to every weekday.
They already have three launch sites for Falcon and can't do 200.
(Also see edit, my first post relied on Apple's autocomplete for maths and it used a short ton, plus point about these numbers corresponding to a mere 100 kg per satellite).
The 160 launches figure includes falcons. Seems like Starship fuels and flight tests faster than Falcon though. And if they manage to reuse second stages, then that eliminates a significant manufacturing bottleneck.
